Shared computing mode and blockchain Technology

1. blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.

2. Of course, this is OK
first of all, blockchain is actually a centralized database or a decentralized database, and all technical units are for better maintenance of the public database. Each node keeps a of data independently. Consensus algorithm is used to achieve the data consistency of the node's account book, and cryptographic algorithm is used to ensure the data can not be tampered, and the data can not be tampered and the security of data sending and receiving; Through the script system, the expression scope of account data is expanded
secondly, financial sharing center involves a large amount of financial data. We can combine the technical characteristics of blockchain with Financial Sharing Center. Next, I will combine the technical characteristics of blockchain with Financial Sharing Center
① distributed storage is a distributed database of the blockchain, and each node keeps a of the data independently. If this is combined with the Financial Sharing Center, The users who can join the "financial data on the chain" in the financial sharing chain are equivalent to the "nodes" in the blockchain network, and each user can keep a of the financial data separately, so as to achieve the purpose of sharing
② tampering is not allowed. A very important feature of blockchain technology is that the data cannot be tampered, To ensure the security of a data in the Financial Sharing Center, we need to consider the security as long as the financial data is involved.
of course, before doing the Financial Sharing Center, you must determine your specific needs, if necessary, first write a framework of the whole project, and then find a formal blockchain development team according to the needs, To help you develop this "Financial Sharing Center", we must pay attention to that before formal cooperation is reached, don't disclose the information of your project casually, in order to prevent the same kind from being copied.

3. Information sharing is the key. The blockchain technology is becoming more and more mature. You can understand the ecological agreement, and the tea instry will have a broader development space

4. Generally speaking, the essence of blockchain should be weak control, sub center, autonomous mechanism, network architecture and coupling connection. The essence of blockchain should be a new social structure in the era of information society, which is completely different from the instrial society. The five core points of blockchain are in common with sharing economy to some extent. The essence of the sharing economy is to abandon the old development mechanism, no longer focus on concentration, and instead use the decentralized social resources in a point-to-point way to let the participants participate in, and pay and benefit in different ways
the two Internet hotspots, blockchain and sharing economy, happen to have sufficient "cooperation space". With the development from theory to practice, the instry has made a lot of bold explorations about the two, and even some challenges to the traditional business model have emerged. In this way, the sharing economy with blockchain will be a new business model and a new subversion of interpersonal relationship. I plan to invest in the blockchain instry. After all, in the Internet era, I searched Guangzhou Xuanling Technology Co., Ltd. on the Internet and looked at the webpage. They are a company engaged in software blockchain intelligent contract development. There are many development cases, and the team is also strong.

5. In modern free economic society, the price of any commodity or its equivalent (currency) changes because of the demand for it: the demand is greater than the supply, and the price rises; If the demand is less than the supply, the price will fall. Although bitcoin is a virtual currency, it also has the characteristics of currency, and its price also changes with the demand.

6. Yes, the central network is authentic. Investment is sure to make money.
